Abstract
The invention relates to a process device for assembling a rear suspension leaf spring and a rear axle of a heavy truck. Slotting ends of two carlings are upward and slotting ends of two beams are downward to be installed and welded into a firm frame, and three supporting feet made of steel angles are respectively welded on the bottoms of the two carlings; and two U-shaped bolt positioning blocks are respectively welded on the centers of the upper parts of the two carlings, each U-shaped bolt positioning block is provided with a rectangular through slot along the longitudinal direction, and the two side surfaces and the undersurface of the each rectangular through slot are respectively provided with a shallow rectangular positioning slot used for positioning a U-shaped bolt. When the rear suspension leaf spring and the rear axle are assembled, four U-shaped bolts with upward openings are arranged in the positioning slots, on the basis of the positioned U-shaped bolts, other parts are convenient and easy to assemble, the assembly efficiency can be greatly improved, and the assembly time is saved.
Description
Technical field
The present invention relates to the process equipment in car production process, particularly a kind of heavy-duty truck rear suspension steel spring and back axle packaging technology equipment.
Background technology
The assembly technology of current truck chassis is generally all adopted with the following method: be first placed on manufacturing line by the bottom of vehicle frame towards sky, vehicle frame spring carrier installs forward and backward steel spring by leaf spring pin, hinge of leaf spring, after fixedly mounting forward and backward bridge with clevis bolt, vehicle frame is stood up, make vehicle frame upper, forward and backward bridge under, and then other vehicle chassis component is installed.The rear suspension steel spring of heavy-duty truck and back axle are assembled, as still adopted said method, then due to the size of steel spring and back axle and weight comparatively large, locate comparatively difficulty in installation process, labour intensity is large and time-consuming.
Summary of the invention
The present invention proposes a kind of heavy-duty truck rear suspension steel spring and back axle packaging technology equipment, it can effectively solve the problem, and the clevis bolt reserved owing to there being position does basis, other parts easily easy to assembly, greatly can improve efficiency of assembling, save time of setting up.
This heavy-duty truck rear suspension steel spring provided by the invention and back axle packaging technology equipment, the blanking of two pieces longeron channel-section steel is made, and two pieces crossbeam is also made with channel-section steel blanking.By two pieces longeron fluting end upward, down, assembly welding becomes a firmly framework to two pieces crossbeam fluting end.Bottom two pieces longeron, weld the leg that three angle steel make respectively; In two pieces longeron upper middle position, weld two pieces clevis bolt locating piece respectively.Clevis bolt locating piece steel are made, and have a larger rectangular through slot along the longitudinal direction, process a more shallow rectangular channel locate for clevis bolt in two sides of groove and bottom surface.This device is used to carry out rear suspension steel spring and back axle when assembling, first by four opening up positioning grooves being placed in four clevis bolt locating pieces of clevis bolt, upper cover plate, additional leaf spring, backing plate, main steel plate spring is put respectively successively in arranged on left and right sides, lifting back axle, in back axle top arranged on left and right sides, bottom plate is installed respectively, finally respectively self lock nut is installed at four clevis bolt thread end and tightens.After rear suspension steel spring and back axle have been assembled, then its integral piece is lifted on vehicle frame.
When adopting this kind of device to assemble, the clevis bolt reserved owing to there being position does basis, other parts easily easy to assembly, greatly can improve efficiency of assembling, saves time of setting up.This kind of device can be widely used in car production enterprise.

Detailed description of the invention
Be described in detail below in conjunction with accompanying drawing.
As shown in Figure 1, Figure 2, shown in Fig. 3, Fig. 4 and Fig. 5, the parts such as the assembly object of rear suspension steel spring and back axle packaging technology equipment---back axle 1, main steel plate spring 2, additional leaf spring 3, clevis bolt 8, upper cover plate 7, backing plate 10 and bottom plate 11 represent with long and two-short dash line, do transparence process.This heavy-duty truck rear suspension steel spring provided by the invention and back axle packaging technology equipment, two pieces longeron 5 channel-section steel blanking is made, and two pieces crossbeam 12 is also made with channel-section steel blanking.Two pieces longeron 5 is slotted end upward, two pieces crossbeam 12 slots end down, and assembly welding becomes a firmly framework.Bottom two pieces longeron 5, weld the leg 6 that three angle steel make respectively; In two pieces longeron 5 upper middle position, weld two pieces clevis bolt locating piece 4 respectively.Clevis bolt locating piece 4 is made with steel, has a larger rectangular through slot along the longitudinal direction, processes a more shallow rectangular channel locate for clevis bolt 8 in two sides of groove and bottom surface.This device is used to carry out rear suspension steel spring and back axle when assembling, first by four opening up positioning grooves being placed in four clevis bolt locating pieces 4 of clevis bolt 8, upper cover plate 7, additional leaf spring 3, backing plate 10, main steel plate spring 2 is put respectively successively in arranged on left and right sides, lifting back axle 1, in back axle 1 top arranged on left and right sides, bottom plate 11 is installed respectively, finally self lock nut 9 is installed respectively at four clevis bolt 8 thread end and tightens.After rear suspension steel spring and back axle have been assembled, then its integral piece is lifted on vehicle frame.When adopting this kind of device to assemble, the clevis bolt 8 reserved owing to there being position does basis, other parts easily easy to assembly, greatly can improve efficiency of assembling, saves time of setting up.This kind of device can be widely used in car production enterprise.
